Ecology
Marine; reef-associated; non-migratory; depth range 0 - 80 m (Ref. 128797). Tropical; 35°N - 35°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.5 cm TL male/unsexed; (Ref. 90102)
Schools are found above branching corals along upper margins of clear lagoon and outer reef slopes. Often associated with branching Acropora. Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980, 120737).
